The natural inequality of the two powers of population and of production in the earth, and that great law of our nature which must constantly keep their efforts equal, form the great difficulty that to me appears insurmountable in the way to the perfectibility of society.
The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.
The power of population is indefinitely greater than the power in the earth to produce subsistence for man.
The greatest talents have been frequently misapplied and have produced evil proportionate to the extent of their powers. Both reason and revelation seem to assure us that such minds will be condemned to eternal death, but while on earth, these vicious instruments performed their part in the great mass of impressions, by the disgust and abhorrence which they excited.
Where there are few people, and a great quantity of fertile land, the power of the earth to afford a yearly increase of food may be compared to a great reservoir of water, supplied by a moderate stream. The faster population increases, the more help will be got to draw off the water, and consequently an increasing quantity will be taken every year. But the sooner, undoubtedly, will the reservoir be exhausted, and the streams only remain.
No limits whatever are placed to the productions of the earth; they may increase forever.
I do not know that any writer has supposed that on this earth man will ultimately be able to live without food.
The moon is not kept in her orbit round the earth, nor the earth in her orbit round the sun, by a force that varies merely in the inverse ratio of the squares of the distances.
The germs of existence contained in this spot of earth, with ample food, and ample room to expand in, would fill millions of worlds in the course of a few thousand years.
